NTI AUDIO/HD VIDEO MATRIX SWITCH
INTRODUCTION
The VEEMUX SM-8X4-HDA (VEEMUX-A) is a versatile multi-input audio/video matrix switch that independently switches eight
sets of incoming YPbPr component video and analog/digital audio signals to any or all of the four outputs. Each input and output
has YPbPr component video, L/R analog audio (balanced/unbalanced), and digital audio on coax (S/PDIF).
Video resolution up to 1920x1080@60Hz is supported with no degradation – guaranteed. An LCD on the front panel indicates the
current connections. The VEEMUX-A can be controlled by four methods: Front Panel LCD with Keypad, RS232 interface,
Ethernet, or optional Infrared Remote. The SM-8X4-HDA is the ideal solution for many applications, such as mission critical
command centers, sports facilities and entertainment venues.
Features
• Supports High Definition and Standard Definition YPbPr component video, S-Video or composite video.
• Audio can be unbalanced analog stereo, balanced analog stereo or digital S/PDIF.
• Supports S/PDIF, DTS Digital Surround™, and Dolby Digital™ 5.1 digital signals.
• Supports 480i (interlaced), 480p (progressive), 720i, 720p, 1080i, and 1080p formats.
• Features break-away audio- allowing audio to be switched independent of video.
• Equipped with volume control: -80dB to 10dB, in 1dB steps.
• Control the switch through Ethernet, RS232, front panel buttons or optional IR remote.
Optional Feature
• Infrared Control (see page 32)- to order, add "IR" to the part number (i.e. SM-8X4-HDA-IR)

INSTALLATION
Connect the Sources
1. Turn OFF power to all video sources (inputs) that will be connected to the VEEMUX-A before connecting or
disconnecting any cables.
2. Connect each video source to the VEEMUX-A using 4CEXT-xx BNC cables. The groups of terminals are labeled INPUT1-8.
and colored cables attach to terminals as follows: green (Y), blue (Pb) and red (Pr). If necessary, use BNC to RCA adapters to
connect the cables to the video sources (see Fig. 1). If the cables used do not have BNC connectors on them but have RCA
connectors instead, use an RCA-to-BNC adapter on each to connect to the VEEMUX-A.

Every unit comes standard with the Front Panel LCD with Keypad, RS232, and Ethernet connection built-in. If desired, the
Infrared option must be requested at the time of the order. The Infrared option requires the purchase of a separate remote control
device (Infrared transmitter) as well as an Infrared receiver to be installed in the VEEMUX-A. No software is involved (see
Infrared Control on page 32). With the RS232 option, there are no external devices to be purchased. NTI provides software
commands as well as a test program to ensure the RS232 functions properly (see page 13 – RS232 Control).
Front Panel LCD with Keypad Control
The front panel LCD and keypad allow the user to monitor switch status and route any display to any video source on the switch.
When the unit is powered up, each monitor is automatically connected to the video source of its equal number (i.e. monitor 1 to
source 1, monitor 2 to source 2, monitor 3 to source 3, etc.). Along with the routing of the inputs (video sources) to the outputs
(monitors) the keypad and LCD allow the users to configure the RS232 control interface. The keypad buttons perform the
following functions.
ESC Escape back to the main display.

Volume Control
The volume level can be adjusted on each output port.
• To increment <▲> or decrement <▼> the volume, use the following command:
<OUT>, <▼>, Double digit output port number, <▲> increment or <▼> decrement, <ENTER>
Ex 1: <OUT> <▼> 03 <▲> <▲> <▲> <ENTER>
This will increment the volume by +3dB (1dB/ step).
Ex 2: <OUT> <▼> 14 <▼> <▼> <ENTER>
This will decrement the volume by -2dB.
• To Mute, use the command:
<OUT>, <▼>, Double digit output port number, the <0> key, <ENTER>
Ex: <OUT> <▼> 03 0 <ENTER>
This will mute output 3
• To Un-mute, use the instruction:
<OUT>, <▼>, Double digit output port number, the <1> key, <ENTER>
Ex: <OUT> <▼> 03 1 <ENTER>
This will un-mute output 3
Memory Functions
There are 100 memory locations(0-99) available to save connection configurations. Location 0 is the power-ON default).
• Saving Connections
To save all current connections, use the following command:
<*>, <OUT>, Memory location, <ENTER>
Ex: <*> <OUT> 5 <ENTER>
• Restoring Connections
To restore connections from memory, use the following command:
<*>, <IN>, Memory location, <ENTER>
Ex: <*> <IN> 5 <ENTER>
Note: If the current switch configuration includes assigned Scan Mode dwell time values (pg. 9), to save the current
configuration be sure to assign a memory location to it. Otherwise, when the VEEMUX-A is powered OFF, all dwell
time values will be erased. Also, saving the configuration as memory location 0 will cause it to be the power-ON default
configuration.
Configurations that are saved into memory locations via
the keypad can be recalled via the web interface (page 23)
and vice versa.
Menu Button
The Menu button is used to configure the RS232 port.
• The baud rate is selected from the “Baud Rate Menu” . To access this menu, use the command:
<MENU>, the <1> key
Next, press the keypad number corresponding with the desired baud rate:
<1> – 9600
<2> – 4800
<3> – 2400
<4> – 1200
Ex: <MENU> 1 1
This will select 9600 baud
• To set the switch address, use the following instruction:
<MENU>, the <2> key, Double digit address (from 01 to 15- the default address is 01)
Ex: <MENU> 2 03
This will set the address at 03

NTI AUDIO/HD VIDEO MATRIX SWITCH
Scan Mode
Scan Mode causes output ports (audio and video) to automatically switch from one audio and video input port to the next
consecutive audio and video input port after a specified period of time (referred to as the dwell time). Audio and video port
switching will continue indefinitely and no ports will be skipped, whether there are audio or video sources connected to them or
not. If desired, the VEEMUX-A can be configured to skip the scanning of specific ports using the RS232 Command Protocol
(page 11) or Telnet (page 14) .
Dwell time settings can be any value from 0 seconds (000) to 255 seconds. A setting of 000 seconds (the default setting)
disables Scan Mode for that output port. If Scan Mode is disabled for a specific port number, then the video or audio to that
output port number will only change as decided by the administrator.
Note: While Scan Mode is enabled, audio and video ports of the same number will switch together. Independent control
of video and audio ports will be disabled. I.e., when video output 1 switches from input 1 to input 2, audio output 1
will also switch from input 1 to input 2.
To configure Scan Mode from the front panel LCD
Press MENU, the following lines will be displayed:
1) Set Baud Rate
2) Set Unit Addr
Press MENU again, the following line will be displayed:
3) Set Scan Mode
Press 3 to select that menu item. The following request will be displayed:
Select Port
Select the output to be programmed using the numeric keys, then press ENTER. The display will show the current Dwell Time
value for that output and ask for a new value.
Current Time: 16
New Time:
Using the numeric keys, enter a value between 0 and 255 and press ENTER. Leading zeros are allowed (000) but the number
should not exceed 3 digits. The Scan Mode dwell setting value 0 will disable Scan Mode for that output port.
Scan Mode dwell time settings can also be configured through the RS232 Command Protocol (page 11), Telnet commands (page
14), or through the Web Interface (page 27).
NOTE: Scan Mode configuration settings can only be saved if they are assigned a memory location via the Keypad
Control (page 8). Otherwise when the power is cycled to the VEEMUX-A, all Scan Mode settings will be erased.
TIP: If the Scan mode settings are stored as memory location 0, they will be loaded each time the VEEMUX-A is
powered ON.
:
NOTE: If Outputs Scanning Sequences (page 27)
Is enabled, Scan Mode as configured at the LCD
front panel will be disabled.
The disabled front panel Scan Mode feature will
be indicated by the message “SCAN SEQUENCE
IS ACTIVE” on the LCD display.

RS232 CONTROL
RS232 enables the VEEMUX to be remotely controlled via RS232. To control the VEEMUX via RS232 the user has three
options:
• write a program that runs on a PC using the Command Protocol (page 11)
• use the Matrix Switcher's Control Program (page 13) provided on the CD
• use the SerTest program (page 13) provided on the CD
Remote Connection
The RS232 Interface is designed to control the switch via serial (RS232) daisy chain connection from any host computer or other
controller with an RS232 communications port.
The pin outs for the DB-9 connector on the unit are as follows:
RS232 Connector (DB-9 FEMALE)
PIN SIGNAL FUNCTION
1
None no connection
2 TXD Transmit Data (RXD at host)
3 RXD Receive Data (TXD at host)
4 DSR Data Set Ready
5 GND Signal Ground
6 DTR Data Terminal Ready
7 CTS Clear to Send
8 RTS Request to Send
9
none no connection
On the DB-9 female connector, pins 4 (DSR) and 6 (DTR) are shorted and pins 7 (CTS) and 8 (RTS) are shorted. Therefore, host
handshaking is bypassed and TXD and RXD are the only active signals. A straight through DB-9 cable (not null modem) will work
for most CPUs. To daisy chain multiple units, use NTI Matrix-Y-1 "Y" cables, except for the last unit connected. (see Fig 6). For a
pinout of the Matrix-Y-1 cable, see page 40. For straight through cable pinouts applicable to various terminal types, see page
39.
Baud Rate
The unit powers up with a default baud rate of 9600 and a fixed data protocol of 8 data bits, no parity and 1 stop bit. The baud
rate can be changed by pressing the MENU button on the front panel keypad. Then select 1 for SET BAUD RATE and select the
desired baud rate of 9600, 2400, 1200 or 300. A data protocol of 8 data bits, no parity, and 1 stop bit is used for communications.
Unit Address
To allow multiple units to be controlled from a single CPU port, the RS232 control interface is designed to allow "daisy chaining"
up to 15 units using the NTI Matrix-Y-1 "Y" cables (sold separately- pin out is on page 40). By setting the appropriate unit address
with the keypad, each unit can be given a unique address (1-15). Then the unit will only respond to commands on the bus if its
address is embedded in the command. To set the unit address select MENU on the front panel keypad. Then select 2 for SET
UNIT ADDRESS and then type the address number (1-15) and (ENTER).
